摘    要:基于迈克尔逊干涉仪原理,提出了在非平静水面情况下探测中低频水下声信号的激光干涉方法。利用携带声波信息的散射光和参考光的干涉结果提取水下声信号的频率信息,并进行了理论分析和实验验证,结果表明,激光干涉法可以准确探测出中低频水下声信号的频率信息。

关 键 词:水下声信号  水表面波  激光探测  干涉

Abstract:A new method is proposed to detect medium and low frequency underwater acoustic signals by means of laser interference based on the principle of Michelson interferometer.The frequency information of underwater acoustic signals can be concluded from the interference of scattered laser beams carrying acoustic wave information with a reference beam.A preliminary theoretical analysis and experimental verification show that it is feasible to detect the frequency information of medium and low frequency underwater...
Keywords:underwater acoustic signals  water surface wave  laser detection  interference
